(1) The acute effects of ethanol on protein synthesis by liver and skeletal muscle were investigated in young (95-100 g) rats. Rats were injected intraperitoneally with ethanol, 75 mmol/kg body wt; controls were injected with isovolumetric 0.15 M NaCl. After 140 min rates of protein synthesis were measured by injection of a large dose of L[4(3)H]phenylalanine and at 150 min rats were killed. (2) Fractional rates of protein synthesis in control animals were approximately four to five times greater in liver than muscle. Absolute rates were, however, comparable in liver and skeletal muscle. Ethanol reduced the fractional rate of liver protein synthesis by 5-20%; the response for muscle was relatively greater (25-30%). The decrease in the amount of protein synthesized by muscle was also greater than that by liver. (3) After 150 min, plasma gamma-glutamyl transferase, alanine aminotransferase, alkaline phosphatase, lactate dehydrogenase and creatine kinase activities were all decreased by 25-60%. Aspartate aminotransferase activity was increased by 42%, though this was not statistically significant. (4) Increased plasma glucose and triglycerides in ethanol-dosed rats indicated that limitations in substrate supply were not mediating factors in reducing protein synthesis. Ethanol was also able to exert its effects in the presence of elevated insulin levels. A direct effect of ethanol, or its metabolites, on protein synthesis, is therefore implied.

Concentrations of sodium, potassium, chloride, inorganic phosphorus, total magnesium, total calcium, iron, urea, creatinine, total protein, albumin, total bilirubin, alkaline phosphatase (ALP), alanine transaminase (ALT), lactate dehydrogenase (LD), creatine kinase (CK), gamma-glutamyltransferase (GGT) and aspartate transaminase (AST) were determined in serum specimens collected from 53 free-ranging mountain reedbuck (Redunca fulvorufula) during live capture using nets. Considerable variations in the concentrations of the enzymes ALP, LDH, CK, GGT and AST were found as well as in the concentrations of creatinine, bilirubin and iron. This wide variation in results seriously questions the usefulness of similar blood investigations on heterogenous groups of mechanically restrained animals.

F344/N rats and B6C3F1 mice were exposed to 0, 1, 3, or 6 ppm methyl isocyanate by inhalation for 6 hr on 4 consecutive days. Deaths of rats were observed following 3 ppm exposures, and mice died after exposures to 6 ppm. Deaths appeared to be related to severe respiratory distress. Survivors in high dose groups lost weight initially, then gained weight at rates equal to controls throughout a 91-day recovery period. Lung weights increased significantly in male and female rats exposed to 3 ppm, but no persistent changes in brain, kidney, thymus, spleen, liver, or testis weights were seen in either mice or rats. Blood and serum from male and female rats were taken for clinical pathology and hematology assessments on day 7 of postexposure, the day prior to the first observed deaths of these animals. No changes or only slight changes were seen in measures of serum alanine aminotransferase, sorbitol dehydrogenase, alkaline phosphatase, or in blood and brain cholinesterase activities. However, serum creatine kinase increased with dose in both males and females. Blood urea nitrogen, creatinine, and methemoglobin were unchanged. No changes were seen in counts of red blood cells or platelets, or in red cell indices. Hemoglobin concentrations and hematocrits were slightly elevated. No changes were noted in absolute leukocyte counts, but counts of segmented neutrophils increased and lymphocytes decreased.(ABSTRACT TRUNCATED AT 250 WORDS)

1. A variety of biochemical measurements were taken periodically in captive northern bobwhite (Colinus virginianus L.), European starlings (Sturnus vulgaris L.), red-winged blackbirds (Agelaius phoeniceus L.) and common grackles (Quiscalus quiscula L.) to determine whether baseline values remain sufficiently stable throughout the year for general clinical use in the absence of concurrent control specimens. 2. Variables included whole blood hematocrit and hemoglobin, plasma lactate dehydrogenase, alpha-hydroxybutyrate dehydrogenase, aspartate aminotransferase, alanine aminotransferase, creatine kinase, butyrylcholinesterase, alkaline phosphatase, glucose, albumin, total protein, creatinine, urea nitrogen, uric acid, cholesterol, and triglycerides, and brain acetylcholinesterase. Butyryl- and acetylcholinesterase were included because of their specific uses in toxicology. 3. Significant seasonal differences were detected for each of the variables except brain acetylcholinesterase in at least one of the species. Significant species differences were detected during at least one season for all of the variables measured. 4. All species were maintained outdoors, but only northern bobwhites came into reproductive condition and showed sex-differences in the clinical variables during their normal breeding season. 5. It was concluded that reference values for the 18 clinical variables measured could be calculated from our data for adult specimens of the species studied, and that results for one species cannot be extrapolated with certainty to any other species. 6. Estimated normal bounds for each of the 18 variables measured by commonly used clinical procedures are presented for reproductively quiescent northern bobwhites, European starlings, red-winged blackbirds, and common grackles.

The authors evaluated the Cobas FARA centrifugal analyzer with respect to pipetting precision and accuracy, instrument temperature, spectrophotometric response, and analytic performance for the assay of five serum enzymes and glucose. Spectrophotometric response, temperature response, pipetting precision, and accuracy were satisfactory. However, sufficient time must be allowed for cuvet contents to reach a stable temperature before measurements are made. Total day-to-day imprecision (within plus between run) was less than 5% (coefficient of variation) for aspartate and alanine aminotransferases (AST; Enzyme Commission classification number [EC] EC 2.6.1.1; and ALT; EC 2.6.1.2); alkaline phosphatase (AP; EC 3.1.3.1); gamma-glutamyltransferase (GGT; EC 2.3.1.2); lactate dehydrogenase (LD; EC 1.1.1.17); creatine kinase (CK; EC 2.7.3.1); and glucose assays. Results compare well with those obtained with other current clinical chemistry analyzers; correlation coefficients were greater than 0.993. Sample-to-sample carryover was negligible, and method linearity was satisfactory for all tests.

Using fully mechanized analytical equipment, interference by haemolysis in the determination of 26 clinical chemical parameters was determined quantitatively by adding haemolysate to serum. Haemoglobin concentrations up to 6.6 g/l caused essentially no interference in the following determinations: albumin (immuno-nephelometric), alpha-amylase, calcium, chloride, cholesterol, cholinesterase, creatinine, iron, glucose, glutamate dehydrogenase, uric acid, urea, sodium, inorganic phosphate, total protein, transferrin and triglycerides. In the presence of haemoglobin, erroneously high values were found for: lactate dehydrogenase (haemoglobin higher than 0.2 g/l), aspartate aminotransferase, potassium and acid phosphate (haemoglobin higher than 1.5 g/l), creatine kinase (haemoglobin higher than 2.5 g/l) and alanine aminotransferase (haemoglobin higher than 3.4 g/l). Erroneously low values were found for bilirubin (haemoglobin higher than 0.8 g/l), alkaline phosphatase and albumin (by electrophoresis) (haemoglobin higher than 1.5 g/l) and gamma-glutamyltransferase (haemoglobin higher than 3.0 g/l).

We obtained enzyme data on normal individuals in conjunction with a large interlaboratory enzyme survey. For the 12 largest peer groups using unique methods, we found a simple relationship between the upper reference limits and the laboratories' results obtained from human-enzyme-supplemented survey serum. A conversion to a common base made possible the merging of data on the normal individuals and interconversion of results by diverse methods. We determined the upper reference limits for serum lactate dehydrogenase, alkaline phosphatase, aspartate aminotransferase, alanine aminotransferase, and creatine kinase for approximately 8000 adult men and women believed to be in good health. Using a technique described here, we believe that the results can be transformed to user-specific units, and that the large data base can be applied to the many diverse enzyme methods in current use. With these data, enzyme survey participants will be able to estimate appropriate reference intervals for their particular method.
